Proxy wrapper provided to launch tasks so they can post callbacks executed inside the renderer.

0: EventLoopProxy<NativeEvent>

Implementations

impl LaunchProxy

pub fn post_callback<F, T: 'static>(&self, f: F) -> Receiver<T>

where F: FnOnce(&mut RendererContext<'_>) -> T + 'static,

Queue a callback to be run on the renderer thread with access to a RendererContext.

The call dispatches an event to the winit event loop and returns right away; the callback runs later, when the event loop picks it up. Its return value is delivered through the returned oneshot Receiver, which can be .awaited or dropped.

The callback runs outside any component scope, so you can’t call Platform::get or consume context from inside it; use the RendererContext argument instead.
